A universal damper mounting system and method for mounting a damper within an opening in a wall includes the use of a plurality of metal straps, each of which is initially formed into an roughly S shape with one leg being longer than the thickness of a wall into which the damper is being installed and also being longer than an opposite leg. The damper includes a rectangular housing with top and bottom peripheral sealing flanges on one side of the housing. A first pair of the straps are abutted against the top sealing flange and a second pair are abutted against the bottom sealing flange with the opposite leg of each strap being folded over a respective one of the top or bottom sealing flanges. The damper is then placed in the wall opening and the terminal ends of the long legs of each strap are bent upward or downward, depending upon the position, to overlap the wall surface. The straps thus serve to retain the damper in the wall.
